Overview HMI to Device Scenarios & Demo Using Web Browsers with OPC DA Using Excel with OPC DA Variety of Application Types HMI/SCADA Telemetry Scenarios Data Collection Systems Design Considerations Review
Connectivity With OPC Standard software to software interface HMI/SCADA OPC Clients One connection: OPC Communications infrastructure decoupled from the HMI/SCADA Improves performance Flexibility Choices OPC Server A OPC Server B OPC Server C
HMI/SCADA to OPC Scenarios One HMI to n Devices via OPC n HMIs to n Devices via OPC
HMI/SCADA to OPC Configuration For your HMI/SCADA package, need to know Where to specify target OPC server(s) Where group update rate is set How to browse for items in the OPC server How to connect tags in HMI to OPC items What the HMI does with OPC Quality Data Information Sources: HMI supplier application notes & documents OPC Server supplier documents
System Design Steps Evaluate & Select OPC Server Configure OPC Server Test with Test Client Validate Values Know what you need and how often Tags or No Tags in OPC Server? Systems are only as good as weakest link
To Tag or Not to Tag? Tags in the OPC Server when... HMI client expects/wants you to Need to Insulate HMI configuration from PLC configuration changes OEM desires insulation from PLC model change Need Easy changes w/o HMI development license
To Tag or Not to Tag? No tags in the OPC server when Need to avoid multiple databases and.. HMI system prefers it this way Benefits of tagging not important to you Retrofitting existing HMI where PLC addresses are in the HMI Existing standards
How Does the Data Get There? Temp 1: 78.9 OPC Client HMI Setpoint: 79.9 68.0 With most HMI s: Reads exception based Writes on demand OPC Client-Server Connection 81.2 78.9 81.2 PLC Communications Network

Wireless/Telemetry Scenarios SCADA Server with n OPC Servers
Wireless/Telemetry Requirements Adjustable timeouts Adjustable protocol timing Automation demotion of offline devices Dialing phone # s w/phone modems Managing dynamic target IP addresses Modbus Variants Industry specific protocols Because of OPC, market demand has created a supply of OPC Foundation Member Solutions that address these unique requirements
OPC to Data Storage Scenarios Logging Data to text or database from 1 OPC Server reading from n Devices Gathering Data from n OPC Servers from n Devices and logging to remote database(s)
OPC - From Live to Historical The Historian writes the data to the data store OPC HDA Server retrieves historical data for display & analysis client application OPC DA Server Gets the live data into the Historian Definition: OPC HDA = Historical Data Access

OPC Foundation International Industry Standard Organization 500+ Member Companies / 100+ end-users Members 3500+ Total Companies Build OPC Products = 22000+ Products The vision of OPC is to be the Foundation for InterOperability for moving information vertically from the data sources through the enterprise of multi-vendor systems (with stops in between ) For moving information horizontally between data sources on different industrial networks from different vendors; Not just data but information. Reliable, Secure Integration is not an Option Collaboration is key to pulling multiple open standards into unified open platform architecture. Success is measured by level of adoption
